Face it Alan - ALL future sims will be compared to GPL and/or NR2k3.
That's simply the lay of the land because pay's sims were always better
than everyone elses. Papy placed the bar, and IMHO, it's the job of
future sims to excel above that bar.
I happen to agree with Tony - rFactor ain't perfect, but it's highly
modable, and there is already an active mod community supporting the
sim.
One last point - at least ISI is *trying* to give us what we want, to
the point that they've gone rogue as far as using a "publisher" is
concerned. They've even delivered a product. It's a whole helluva lot
better than EA's continuing effort to deliver a decent nascar sim.
